Hi Folks, I know it possible to customize ENVI adding custom functions. Now, I am more wondering in adding new grpahical objects to Envi. There are already objects that allow to create an AOI for ex. Let's say that I would like to create a custom cross that I can move around in the full resolution display to mark a pixel that I would like to analyse with a custom function. Is this possible? Thank you for the answer. Cheers, Nuno
